The manager of a downtown Pittsburgh McDonald's has been arrested for allegedly conducting drug activity inside the restaurant, and the district attorney has threatened to padlock that location and two others downtown.

"I want a settlement tomorrow, and if we don't have a settlement tomorrow, my guys have been directed to file the complaints," said District Attorney Stephen Zappala, after meeting with a McDonald's attorney Tuesday.

Port Authority police said John J. Eckard, 48, of Bethel Park, was arrested Monday and charged with conspiracy and possession with intent to deliver after he did not show up for work at the Smithfield Street McDonald's.

Zappala said the arrest is part of an ongoing effort to rid the downtown business district of nuisance crimes. His office is promising to say more at a joint news conference with the Pittsburgh Downtown Partnership in Market Square later this week.

Zappala's office has notified McDonald's headquarters that nuisance proceedings will begin to shut down the fast-food chain's restaurants on Smithfield Street, Wood Street and Liberty Avenue unless the company begins working to fix the problem.

"They responded immediately and they said, 'We want to work with you.' We've given them the benefit of the doubt that they were not aware of the problems that were being created around their stores," Zappala said.

Images from surveillance cameras show what police say is drug dealing in and around the three McDonald's locations. Zappala said he mapped more than 100 drug-related arrests in and around those restaurants over a matter of months.

"It's 35 pages long and outlines a substantial number of drug transactions in and around those stores, and the basis upon which I've concluded that they're nuisances and they have to change how they do business," Zappala said.

Debra Andrews, vice president of quality, service and cleanliness for McDonald's Pittsburgh region, issued this public statement:

"We take these allegations seriously. Operating safe restaurants will always be a priority for McDonald's. We have long-standing safety and security policies and procedures in place at all of our U.S. restaurants. McDonald's and our franchises are fully cooperating with the district attorney's office and police department in this matter."

Eckard's charges stem from what police said were two separate drug deals inside his restaurant in February.

The criminal complaint alleges that Eckard sold 11 Clonazepam pills for $20 to a confidential informant in a bathroom, and a customer identified as "Tommy" sold the same informant five Xanax pills for $20.
